Abstract

A cart includes a flat base, at least three wheels coupled to the flat base onto one flat side of it and a flexible casing coupled to the flat base along a circumference of the flat base. The flexible casing is extendable in a direction that is substantially perpendicular to the flat base between a first casing position and a second casing position.

1 . A cart comprising:
 a flat base;   at least three wheels coupled to the flat base onto one flat side of it;   a flexible casing coupled to the flat base along a circumference of the flat base, the flexible casing being extendable from the flat base's side opposite to the wheels side, in a direction that is substantially perpendicular to the flat base between a first casing position and a second casing position.   
     
     
         2 . The cart of  claim 1 , wherein the flexible casing folds, in the first casing position, to employ a layer above the flat base, wherein a thickness of the layer is no more than 15% of a thickness of the flat base. 
     
     
         3 . The cart of  claim 1 , wherein the flexible casing comprises at least one opening on at least one of faces of the flexible casing. 
     
     
         4 . The cart of  claim 3 , wherein the flexible casing comprises at least one covering arranged to cover the corresponding at least one opening. 
     
     
         5 . The cart of any one of  claim 1 , further comprising a handle coupled to the flat base, the handle is switchable between a first handle position and a second handle position with respect to the flat base, such that the handle adds to a total thickness of the cart no more than 15% of a thickness of the flat base when in the first handle position. 
     
     
         6 . The cart of  claim 5 , wherein the handle comprises a first handle-frame pivotally coupled to the flat base. 
     
     
         7 . The cart of  claim 6 , wherein the first handle-frame is releasably fixed at at least one first predetermined angle with respect to the flat base, when in the second handle position. 
     
     
         8 . The cart of  claim 6 , wherein the handle further comprises a second handle-frame pivotally coupled to a free end of the first handle frame. 
     
     
         9 . The cart of  claim 8 , wherein the second handle frame is releasably fixed at at least one second predetermined angle with respect to the first handle-frame. 
     
     
         10 . The cart of  claim 9 , wherein the handle is a rope or a chain. 
     
     
         11 . The cart of  claim 1 , comprising at least two first wheels having a diameter ranging between 2-5 cm and at least two second wheels having a diameter ranging between 6-10 cm. 
     
     
         12 . The cart of  claim 11 , wherein at least some of the at least two first wheels and the at least two second wheels are foldable. 
     
     
         13 . The cart of  claim 1 , further comprising at least one storing connector arranged to removably connect the cart to a dedicated support.
